2 Claims.

This invention relates to surface water disposal from pavements.

. Thisinvention has utility when incorporated sewer waste intake assembly and connection in the form of grating and curb inlet to the sewer or duct.

Referring to the drawings:

Fig. 1 is a plan view of an embodiment of the invention as the elements of a paving fixture;

Fig. 2 is a section on the line 11-11, Fig. 1, with the main frame and grating,.showing the curb section in elevation;

Fig. 3 is a side elevation of the grating;

Fig. 4 is an end elevation of the curb outlet andfinish portion;

Fig. 5 is a side elevation of the main frame;

Fig. 6 is an end elevation of the supplemental frame adapted to fit with the main frame; these Figs. 3, l, 5 and 6 being in distributed grouping;

Fig. '7 is a fragmentary plan View of a portion of the main frame of Fig. 5;

Fig. 8 is a fragmentary view in plan of a portion of the supplemental or curb frame of Fig. 6;

Fig, 9 is a section on theline IXIX, Fig. '7, showing assembly of the grating with the main frame;

Fig. 10 is a fragmentary front elevation of the curb finish; 1

Fig. 11 is an elevation of the front or cross portion of the sectional frame to be mounted on the primary frame in carrying up from pavement foundation to pavement height;

Fig. 12 is a fragmentary plan view of the sectional U-frame of Fig. 11;

Fig. 13 is a view,with parts broken away, of the foundation frame installed in the pavement for finish flush with the pavement;

Fig. 14 is a view similar to Fig. 13, of the foundation frame installed in a pavement wherein there is supplemental surfacing and extension of the frame from the frame base or major sec tion; and

Fig. 15 is a fragmentary plan view, wherein the fixture may be as to the main frame installed with curb continuity line running therepast and the curb portion of the frame to be later or subsequently installed.

Partially circular lower base flange (Fig. 1) has uprising brace flanges 2 therefrom to threesided frame portion 3 forming U with open side 4 (Fig. 5). This Uashaped main frame portion 3 on the inner side is inwardly extending flange 5 (Fig. '7) upon which may rest bounding flange (5 of grating i. In the forming of this primary frame, say of cast iron, there may be anchored therewith in lug 8 upstanding threaded portion or bolt ii so that at seat It! in the grating 1, nut It may coact with this bolt 9 in anchoring this grating in position.

In carrying out the invention herein upon 5 pavement base 82 (Fig. 13), this primary frame it may be located. The running of pavement foundation as cement I3 is then effected continuously therealong and thereover, say as protected by cardboard sheet M (Fig. 15) in con- 10 junction with curb marking pavement limit form it, which, as the pavement is run, may be taken up for the installation of curb, whether cast of concrete or trimmed stone curbing. In either event, as the curbing form I5 is removed, supple- 15 mental frame having base flange l6 (Fig. 6) and upright brace portion I1 with upstanding supplemental frame It may be placed in position to have the base flange l6 register with the base flange of the primary frame and this upright 20 portion is extend between the lugs of the U providing space from open portion 4. This upright portion i8 is in the curb line thus ready to receive finish or trim l9 (Figs. 4, 10) along the curb top with terminal depending portions 20 to 25 ride astride the upper portion of the free ends of the flange 3 and there be anchored in position by bolts ill from openings 22 in the upright l8 and through openings 23 in the under side of the curb finish l9. There is accordingly left in reg- 30 ister position clear-Way or opening inlet 24 under this curb finish and laterally from the grating l as the major port for this waste water connection flow from the pavement surface as well as through the grating 1.

There is economy in the installation hereunder for the reason that the primary frame may be set on the pavement base !2 and the run of pavement foundation It be continuous over this primary frame with the primary frame thereby anchored with and as a unit of the pavement proper. This is simply effected in the type of concrete pavement wherein the foundation is the surface direct to the pavement face.

In other instances wherein on pavement base i2 there is laid foundation 25 (Fig. 14) in order that there may be finish surface whether of block or asphalt 26, it is in order hereunder similarly to place supporting flange l on the base l2. However, in lieu of the frame 3 there is minor frame 5 21 having inwardly extending lug or flange portion 28 with bolts 29 which may have nuts 30 to anchor sectional U-frame 3| as the carry-up portion from the pavement foundation 25 to position flush with the surface of the pavement 26.

These bolts 29 may be inserted in the primary frame and held in position by the concrete so that the U-section 3| may be anchored therewith.

In the layout wherein the pavement foundation 25 falls short of the extent of the finished pavement surface, the clearway in the U-frame is not placed with a grating but with an insert strip or plate, say of sheet metal, on the lower ledge to bring to flush position in order that pavement continuity may be thereacross. Upon locating then placing U-frame 3| as a section to complete the primary frame, the grating may be installed as normally thereon and this followed with the curbing section in the sequence after the pavement foundation which has effected the anchoring of the primary frame.

While the pavement base l2 may be continued under the curb line or form IS in thereby providing support for the supplemental frame base flange Hi, there is preferred additionally effecting an interlock between this primary frame having the base I and this supplemental frame having the base l6, which interlock is herein shown as projecting lug 32 (Fig. 6) having slot 33 in providing a fork, one at the inside of each of the legs of the U-frame 3. When so brought into position as to the bolt holes 34 in the frame 3, locking may be effected between these forkextensions 32 and the frame 3 by bolts 35. These bolts 35 are anchored in the cement for the application of the nuts thereto after the placing of this supplemental curb section.

What is claimed and it is desired to secure by Letters Patent is:

1. The method of providing sewer waste connection from a pavement comprising, locating a U-shaped frame portion for a sewer inlet adjacent a curb line, running a pavement therepast in pavement continuity to anchor said frame with simultaneously defined clearance for curbing, thereafter providing curb side addition for the frame portion to complete the frame by thrusting .the addition horizontally into interlocking relation against vertical shifting out of register, and establishing a curb in common with said addition.

2. A pavement waste water fixture embodying a U-shaped main frame determining a base level, and a minor coincident base level additional frame shiftable horizontally into closing position between the legs of the main U-frame, said minor frame having parallel projecting arms located by said shifting into interlocking position with the legs to position the frames for retaining their base portions in a common plane.
